"Thin piece of board duct-taped to the arm of the chair (with piece of old shirt as base, so no glue gets on the chair) puts the mouse immediately under your hand; the leather glued to the top of the board provides a smooth but low-slip surface for the mouse; and the packing styrofoam from the end of the PC tower (reinforced with duct tape, of course), sits on your lap to put the wireless keyboard at your fingertips."
